  • Fault Diagnosis in Highly Dependable Medical Wearable Systems
    • Abstract: Abstract High levels of dependability are required to promote the adherence by public and medical communities to wearable medical devices. The study presented herein addresses fault detection and diagnosis in these systems. The main objective resides on correctly classifying the captured physiological signals, in order to distinguish whether the actual cause of a detected anomaly is a wearer health condition or a system functional flaw. Data fusion techniques, namely fuzzy logic, artificial neural networks, decision trees and naive Bayes classifiers are employed to process the captured data to increase the trust levels with which diagnostics are made. Concerning the wearer condition, additional information is provided after classifying the set of signals into normal or abnormal (e.g., arrhythmia, tachycardia and bradycardia). As for the monitoring system, once an abnormal situation is detected in its operation or in the sensors, a set of tests is run to check if actually the wearer shows a degradation of his health condition or if the system is reporting erroneous values. Selected features from the vital signals and from quantities that characterize the system performance serve as inputs to the data fusion algorithms for Patient and System Status diagnosis purposes. The algorithms performance was evaluated based on their sensitivity, specificity and accuracy. Based on these criteria the naive Bayes classifier presented the best performance.

  • A Wideband Digital-to-Frequency Converter with Built-In Mechanism for
           Self-Interference Mitigation
    • Abstract: Abstract A digital-to-frequency converter (DFC) assisted by a built-in-self-measurement mechanism is presented. It demonstrates the capability to overcome oscillator pulling that is caused by the high-speed digital frequency-tuning signal that is fed into the DFC’s digitally-controlled-oscillator (DCO), thereby allowing the DFC to accommodate high-rate modulating data. Thus, by placing replica images and quantization noise far away from the transmitted carrier, the presented DFC is suitable for wireless applications having the most demanding spectral mask requirements, without necessitating RF filtering in the transmitter’s signal path. The proposed solution, designed with minimum overhead, reduces the extent of injection pulling experienced by the digitally controlled oscillator (DCO) due to ΣΔ dithering applied to its capacitor bank by adjusting the phase between the aggressor and victim signals through a digitally controlled delay (DCD) line. The proposed calibration and compensation scheme for the DCD is autonomous and simple computationally. The proposed solution has been demonstrated in a transmitter of a commercial cellular CMOS system-on-chip (SoC).

  • A 65nm CMOS Ramp Generator Design and its Application Towards a BIST
           Implementation of the Reduced-Code Static Linearity Test Technique for
           Pipeline ADCs
    • Abstract: Abstract This work presents an efficient on-chip ramp generator targeting to facilitate the deployment of Built-In Self-Test (BIST) techniques for ADC static linearity characterization. The proposed ramp generator is based on a fully-differential switched-capacitor integrator that is conveniently modified to produce a very small integration gain, such that the ramp step size is a small fraction of the LSB of the target ADC. The proposed ramp generator is employed in a servo-loop configuration to implement a BIST version of the reduced-code linearity test technique for pipeline ADCs, which drastically reduces the volume of test data and, thereby, the test time, as compared to the standard test based on a histogram. The demonstration of the pipeline ADC BIST is carried out based on a mixture of transistor-level and behavioral-level simulations that employ actual production test data.

  • Reliability Analysis of Fault-Tolerant Bus-Based Interconnection Networks
    • Abstract: Abstract Multi-processor systems need interconnection networks (INs) in order to make the connection among the processors, memory modules, and nodes. Bus interconnection network is the simplest and least expensive one among all the INs. Therefore, bus network is easily understood and preferred by manufactures for implementation. However, a bus network is inherently a non-fault tolerant and blocking network. To cope with these problems, a solution is to use several buses in parallel on a network. Based on this idea, various schemes can be designed for a bus network: (1) Multiple-bus with full bus-memory connection, (2) Multiple-bus with single bus-memory connection, (3) Multiple-bus with partial bus-memory connection, and (4) Multiple-bus with class-based memory connection. On the other hand, a metric for the efficiency of fault-tolerant systems is its reliability. Although, there is no detailed analysis of the reliability of bus-based networks, this paper presents accurate and complete reliability analysis of bus-based networks to achieve these aims: (1) Determining the most efficient design of bus-based networks in terms of reliability, cost-effectiveness, and blocking issues, (2) Providing new methods for evaluating the performance of bus-based networks.

  • Interconnect Reliability Analysis for Power Amplifier Based on Artificial
           Neural Networks
    • Abstract: Abstract In order to learn the interconnect reliability of the complicated integrated circuit, a power amplifier 3D model is constructed and analyzed. The modeling and computation are completely automatic using the APDL. In order to predict the interconnect reliability of the power amplifier for the given design index effectively, the artificial neural networks model is used, then the prediction can be done fast. Training the simulation data from ANSYS, the neural network is used to model the relationship between the input and output. Then, a reliability database can be obtained which can help the designer to get the reliability performance of any design solution and the tradeoff decisions on the transistor’s size and the operation condition.

  • An Efficient Contact Screening Method and its Application to
           High-Reliability Non-Volatile Memories
    • Abstract: Abstract In modern automotive designs double contacts are mandatory to achieve high reliability products and avoid field returns due to contact issues during the lifetime of the product. Using double contacts in compact digital IPs like RAM, ROM or NVMs leads to a dramatic area penalty. High area efficient NVMs are using shared contacts to minimize the area needed to realize the NVM bit cells. Using double contacts would lead to an area increase of approximately 50 % of the NVM memory plane. The high quality standard defined for automotive applications can only be fulfilled with a sophisticated contact screening procedure. This work will present a contact screening procedure which is able to detect contacts with a resistivity outside the main contact resistivity distribution. Those outliers have a potential danger to fail during lifetime as shown in this paper.

  • A Jitter Injection Signal Generation and Extraction System for Embedded
           Test of High-Speed Data I/O
    • Abstract: Abstract An instrument for on-chip measurement of transceiver transmission capability is described that is fully realizable in CMOS technology and embeddable within an SoC. The instrument can be used to inject and extract the timing and voltage information associated with signals in high-speed transceiver circuits that are commonly found in data communication applications. At the core of this work is the use of ΣΔ amplitude- and phase-encoding techniques to generate both the voltage and timing (phase) references, or strobes used for high-speed sampling. The same technique is also used for generating the test stimulant for the device-under-test.

  • A Comprehensive FPGA-Based Assessment on Fault-Resistant AES against
           Correlation Power Analysis Attack
    • Abstract: Abstract The secret key used in a cryptosystem can be retrieved by physical attacks such as side-channel analysis (SCA) and fault analysis (FA) attacks. Traditionally, countermeasures for different physical attacks are developed in a separate fashion. To lay a solid foundation for countermeasure development for the emerging combined attacks, it is imperative to thoroughly study how the countermeasure for one attack affects the efficiency of other attack. In this work, we use a FPGA-based platform to investigate whether and how the FA countermeasure can influence the efficiency of the correlation power analysis (CPA) attack. Unlike the previous work using simulations on the S-Box only, our assessments are based on the FPGA emulation of the entire AES. In addition to considering different error detection codes, we compare the key retrieval speed of the CPA attack in the scenarios of using different power models, redundancy types for fault detection, modules under fault protection, and practical FPGA synthesis optimization. Furthermore, we propose a new countermeasure that integrates dynamic masking and error deflection to simultaneously thwart CPA and FA attacks. Experimental results show that for 100,000 power traces, our method successfully prevents the key leakage while other methods leak at least five AES subkey bytes. Meanwhile, our simulation also confirms that the proposed method reduces the success rate of FA attacks by up to 90 % over the other methods.

  • The Faults Diagnostic Analysis for Analog Circuit Based on FA-TM-ELM
    • Abstract: Abstract Developing fault detection is very important for improving the equipment reliability and saving energy consumption. As compared with neural networks, extreme learning machine (ELM) is based on statistical learning theory, which has advantages of better classification ability and generalization performance. This paper presents a novel approach for fault detection and diagnosis based on Firefly-Chaos Algorithm and Extreme Learning Machine. The experiment result indicates this proposed method is effective for Analog Circuit fault detection and diagnosis and the model generalization ability is favorable.

  • Security Path: An Emerging Design Methodology to Protect the FPGA IPs
           Against Passive/Active Design Tampering
    • Abstract: Abstract Modern FPGAs have a great market share in hardware prototyping, massive parallel systems and reconfigurable architectures. Although the field-programmability of FPGAs is an effective feature in the growth and diversity of their applications; it has caused security concerns for IPs/Designs on FPGAs. Recent researches show that a reliable mechanism is required to protect the IPs/applications on FPGAs against malicious manipulations during all stages of design lifecycle, especially when they are operating in the field. In this paper, we propose a new tamper-resistant design methodology (Security Path methodology) and a revised security-aware FPGA architecture. This methodology protects the configured design against tampering attacks in parallel with the normal operation of the circuit. When the attack is discovered, the normal data flow is obfuscated and the circuit is blocked. Experimental results show that this methodology provides near full coverage in tampering detection with overhead of 12.32 % in power, 12 % in delay and 38 % in area.

  • Impact of Fin-Height on SRAM Soft Error Sensitivity and Cell Stability
    • Abstract: Abstract FinFET technology has become the most promising alternative to continue CMOS scaling due to its improved short channel effects. Design flexibility reduces on FinFET based circuits such as SRAM cells due to the effective channel width is determined by an integer number of fins. In this work, the impact of fin height size of FinFET transistors on the simultaneous behavior of soft error sensitivity and SRAM cell static noise margin is investigated. 3-D TCAD Sentarus environment is used to quantify the amount of collected and critical charges of an SRAM cell due to a heavy ion strike while Mix-Mode Hspice-TCAD simulation is used for stability analysis. Even more, the influence of process variations on sensitivity to soft errors and cell stability is considered. A 10 nm-SOI Tri-Gate FinFET technology is used. Results show that increasing the fin height of FinFET transistors considerably increases SRAM cell sensitivity to soft errors but improves its stability. This suggests that the optimum fin height value of FinFET transistors of an SRAM cell depends on the best tradeoff between soft error robustness and stability.

  • An SEU-Resilient SRAM Bitcell in 65-nm CMOS Technology
    • Abstract: Abstract This paper presents an SEU-resilient 12 T SRAM bitcell. Simulation results demonstrate that it has higher critical charge than the traditional 6 T cell. Alpha and proton testing results validate that it has a lower soft error rate compared to the reference designs for all data patterns and supply voltage levels. The improvement in SEU tolerance is achieved at the expense of 2X area penalty.

  • High Performance Significance Approximation Error Tolerance Adder for
           Image Processing Applications
    • Abstract: Abstract Addition is one of the fundamental arithmetic operations which are used extensively in many VLSI systems such as microprocessors and application specific DSP architectures. In this paper, the Significance Approximation Error Tolerant Carry Select Adder (SAET-CSLA) is constructed, which is efficient in terms of accuracy, power and area. While considering the elementary structure of an image processing applications, it is a combination of the multipliers and delays, which in turn are the combination of the adders. This research paper describes the Algorithmic strength reduction technique which leads to a reduction in hardware complexity by exploiting the significances. This transformation is basically implemented for the reduction in the power consumption and area efficient of Very Large Scale Integration (VLSI) design or iteration period in a programmable Digital Signal Processing (DSP) implementation. The significance approximation error tolerant adder is designed using full adder and approximate full adder cells with reduced complexity at the gate level. The performance of 16 bit conventional Carry Select Adder (CSLA), 16 bit Error Tolerant carry select Adder (ET-CSLA) and proposed Significance Approximation Error Tolerant Carry Select Adder (SAET-CSLA) are compared. For all the 216 input combinations, comparison is made between existing and proposed CSLA adders and the error tolerance analysis is carried out for accuracy improvement. Application of image processing is carried out using proposed SAET-CSLA.

  • Real-Time Adaptive Test Algorithm Including Test Escape Estimation Method
    • Abstract: Abstract This work aims to reduce the test time per chip, but affect the quality of the products only as little as possible compared to the conventional semiconductor test. For that purpose, a simulation software has been developed that performs adaptive test simulations based on real data and test results of conventional production testing. Products has been analyzed and both the potential for test time savings and the resulting loss of quality are determined. Finally, it is shown that by the intelligent omission of tests, compared to conventional testing procedures, test time reduction of up to 50 % can be achieved. In contrast, there are only few defective components that are not detected by the adaptive test procedure and which reduced the quality of products. In best case, the fraction of test escapes was under 40 ppm. To handle the potential risk of test escapes this paper also introduces a statistical estimation method.

  • A New Capacitance-to-Frequency Converter for On-Chip Capacitance
           Measurement and Calibration in CMOS Technology
    • Abstract: Abstract In this paper, a new capacitance-to-frequency converter using a charge-based capacitance measurement (CBCM) circuit is proposed for on-chip capacitance measurement and calibration. As compared to conventional capacitor measurement circuits, the proposed technique is able to represent the capacitance in term of the frequency so that the variations can be easily handled in measurement or calibration circuits. Due to its simplicity, the proposed technique is able to achieve high accuracy and flexibility with small silicon area. Designed using standard 180 nm CMOS technology, the core circuit occupies less than 50 μm × 50 μm while consuming less than 60 μW at an input frequency of 10 MHz. Post-layout simulation shows that the circuit exhibits less than 3 % measurement errors for fF to pF capacitances while the functionality has been significantly improved.
